Inventor ARTHUR WILLIAM EXCELL JXLJLL? Altorney Patented Nov. 17, 1953 AND PRINTING MEANS Arthur William" Excell, Thornton Heath, England, assignor to Powers-"Saunas.Accounting Machines Limited, London,-

company England, a British Application August 22, 1950', Srial'No. 180,728 Claims priority,application Great Britain September 5, 1949 16 claims; (01. 101 -93) This invention relates to machines for printing on statistical record cards. 7

It is sometimes desired to print on a record card such information as a name and address together with certain other data such as a state-'- ment of a balance standing on a mortgage or otheraccount and heretofore this has usually been; accomplished by manually operated posting machine's. v

It is a main object of the present invention to provide a record card controlled machine which during a single passage of a card through the machine will print in a plurality of horizontal lines onthecard information obtained by sensing one'or more record cards, such information consisting, for example, of a name and address and data such as a statement. 7

With this object in View it is, according to one aspect of the invention, proposed to sense data from two associated cards one of which has perforated therein the data comprising thestateme'nt andan identification reference number, the other having perforated therein the name and address to be associated with the statement together with the same identification reference number, the combined data being printed on the card bearing the perforations representing the statement. By this means the card having the name and address perforated therein can be employed as a stock card for use whenever it is desired to associate a, statement there\vi th. V

To distinguish a record card from a card to be printed on, a record card having the name and address perforated therein will hereinafter be referred to as a stock card and this term is to be understood as also including a record card bearing all the information to be printed on a different card whether or not the information contains a name and address or whether it contains other data to be printed on said different card.

Further, for the purposes of distinction herein,

a card to be printed on, whether or not it also has data" perforated therein, will be hereinafter referred to as a"pos'ting card.

According to the invention a method of'p'osting information on a card consists of the steps of feeding posting and stock cards in succession through a machine provided with a, sensing means and printing mechanism, retaining the posting card in printing position for a plurality of consecutive cycles of the machine; retaining the stock card in sensing position for aplurality of consecutive cycles of the machine and'sensi'g a different-field-or fields of the card'du'ring each" All cycle, transmitting the data sensed during each cycle to theprinting mechanism and printing the data on the posting card, and advancing the post ngcard to a newline printing position during each sensing of the stock card, whereby data sensed during consecutive cycles while the stock card s in sensing position is printed in different l ne positions on the posting card during the single passage of the posting card through the machine.

Fu'rthena machine for printing on a card cornpr ses sensing means and printing mechanism, means to feed posting and stock cards in succes-' s on through the machine, means to retain-a pos ng card in printing position for a plurality of consecutive cycles of the machine, means to printing mechanism operable in timed relation the stock card is printed in successive line positions on the posting card during a single passage of the posting card through the machine.

Also according to the invention a machine for printing on cards comprises a positively rotated main shaft, an auxiliary shaft driven by the main shaft through reduction gearing so that the main shaft makes a predetermined number of revolutions for each revolution of the auxiliary shaft, sensing means operable by the main shaft to sense data recorded on a record card, printing mechanism operable in timed relation with the sensing means and including type elements and associated hammer mechanism to print an impression on a record card, transmission elements operable by the sensing means to effect setting of the type elements in accordance with the data sensed from a record card, means to feed a posting card and a stock card in succession to the sensing means, means to arrest each card in a position for sensing by the sensing means and to retain a stock card in sensing position for a plurality of sensing operations effected during consecutive cycles of the main shaft, means operable by the auxiliary shaft to determine the card field or fields sensed during each cycle of the main shaft, and stop means operable in timed relation with the main and auxiliary shafts to locate the posting card in successive line printing positions with respect to the type elements, whereby data sensed from the posting card is printed in one line thereon and data sensed from different fields of the stock card during successive sensing operations efiected in respect thereof is printed in successive line positions on the posting card during a single passage of the posting card through the machine.

In order that the invention may be more clearly understood an embodiment thereof will be described by way of example with reference to the accompanying diagrammatic drawings in which:

Figure 24 is a view similar to that of Figure 1C but shows an alternative form of receiver mechanism whereby posting and stock cards are delivered to receivers in the reverse order from that in which they are delivered by the mechanism shown in Figure 1C.

Referring to the drawings, the machine illustrated in Figures 1A, 1B and 1C, and in Figures 3A, 3B and 30 respectively is, in general, similar to that shown in Figures 1 and 2 respectively of British patent specification No. 478,597 but, as hereinafter described, contains modifications permitting the present invention to be carried into effect. The machine comprises a magazine I, Figures 13 and 3B, in which is placed a stack or pile of cards containing alternate posting cards and stock cards so that a posting card is fed from the magazine in precedence to a stock card. As will hereinafter appear in the machine about to be described one posting card and its associated stock card is fed from the magazine during five successive cycles of the main shaft 2 of the machine and to avoid card feeding at each cycle of the main shaft means hereinafter described are provided to prevent cards being fed from the magazine except during predetermined cycles of the main shaft.

Cards fed from the magazine are delivered to a sensing chamber comprising fixed pin plates 3 and 4, Figure 5, between which the cards are fed. The posting card is retained in the chamher for one cycle only of the main shaft while the stock card is retained therein for four cycles of the main shaft. The cards are retained in the sensing chamber by card stops 5 and 6 described below, the card stops being operated from an auxiliary shaft 1 driven from the main shaft 2 by a compound train of reduction gearing 8, 9, I0 and II, Figure 3B, in the ratio of 5:1. This auxiliary shaft 1 also controls other operations of the machine as will be described below.

The posting card is arrested in sensing position by the card stop 5 and on being released by the stop 5 is fed to a printing position at which it is controlled by a further card stop comprising two blocks l2, Figures 12 and 13, while receiving a succession of printed impressions from type wheels l3, Figures 18, 3B and 5. During each fifth cycle of the main shaft the posting card is released from printing position and the stock card from the sensing chamber and both cards are delivered to card receivers l4 and I5, Figure 3C or Figure 24 as hereinafter described, so that the cards which were alternately disposed in the pile in the magazine I are delivered from the machine as two sorted packs containing posting and stock cards respectively.

Card feeding and sensing mechanism The cards are fed from the magazine I by means of a picker l6, Figure 3B, and feed rolls the picker 6. s e fe ed by an ecce rtic stra 4. o w c centric 2.5 is. secu ed to the main shaft 2.

To avoid feeding cards except. on the first and second cycles of a succession of five.- cycles. of the main shaft 2,, connection between the, arm 22 and eccentric strap 24 is.- eiiected' by; a. connecting arm 26- free on the: spindle 2 3 and to which the eccentric strap. 241 is connected. Thearm 26 is connected: by a. spring 21. to afurther connecting arm 28 fixed to spindle 23a and: providedv with an abutment, shown, as a lateral pin 29. A cam 33, Figure LB, is secured. to the aux iliary shaft 1 and co-operates with a roller 3;]: on a bell crank 32 pivoted about. a spindle 33. mounted in a bracket 34. fixed tov the side of the machine frame. A nose 35 is formed on. the bell crank 32 and acts as a latch, to engage an abut-. ment shown as a pin. 36. extending laterally from an arm 22a also mounted on the spindle 23. When the bell crank-32 is; in the position shown in Figure 1B the nose35engages the pin 36 and prevents the picker l6= frommakingits full backward stroke. Accordingly the picker does not become engaged behind the bottom card contained in the magazine and thus whilst being governed by the nose 35 prevents the feeding of cards from the magazine. During this restrained movement of the arms 22'; 22a the spring 21 is extended and the arm is movedaway from the pin 29. The cam controls the movement of the bell crank 32 and permits free-reciprocation of the arms 22-, 22a onlyduring the first two successive cycles of a series of five cycles.

The cardisdelivered by the rollers l'l-and succeeding pairs of similar rollers between the fixed pin plates 3' and 4-, the cardson beingmoved into the sensing chamber being arrested by the card stop- 5 or card gate or 6 as hereinafter described. The card stops 5 and 6 arefixed to the upper ends of square pillars 31 and 3'8;respec-' tively, Figures 5 and -6, each pillar being guided at its lower end in a bracket and the pillars being urged in an upward direction by springs 40; 4| respectively.

The card stops are controlled-by two cams 4 2" only one of which is shownin Figure 6 the cams being mounted for rotation with the auxiliary shaft 7. carried on a link 44' pivotally connected at 451 to a guide plate 45 pivoted at to a bracket48.,

A latch 451s pivoted atfl and isconnected with the plate 46 by a spring 50, Figure 7, the. end of the spring 50 which is connected'to thel-atch 49 being anchored to a spring post 5! which-also.

serves as an anchorage for a spring 52 connect: ing the latch 49' with a latch 53, To eachof the,

pillars 31 and 38 is secured a square pin 541over. which the latch 53 engages. As the cam rocks, the plate 46 in a counter-clockwise. directionthe;

latch 53 is released from thesquare pin 54 and the card stop associated therewith is ,urged up:

wards to card arresting position by. the spring 40 or M, as appropriate. To open/the, card stop after it has been moved to card arresting pos1-,-.

tion there is provided .a. subsidiary shaft -55;. F-ig;-.

Each cam co-oper'ates with aroller 4 3 1 arresting position. The latch: 53

ures; 1B, 5 and 6., supported in bracket 48, the shaft being rocked in a clockwise.- direction, as viewed in Figures 5 and 6', by acam 50 mounted on the main, shaft 2, see Figure 1B. A lever '51, Figure 6,. mounted on auxiliary shafi; 55 is. moved downwards by the shaft and depresses a pin 58. projecting laterally from the pillars 11' or 38 thus urging the pillar downwards against its; spring and withdrawing the card stop from card is. then again. engaged over the square pin 54;

As? will hereinafter appear the card stops- 5 and 6: are so. operated during five successive cycles of the main shaft 2 that the stopraised and restored during the first cycle, the stop 6 is raised during the second cycle and is restored towards the end ofthe third cycle, and the stop 5' is. again raised during the fourth cycle and restored towards the end of the: fifthcycle. It is, therefore, required that" the lever 51 does, not restore a card stop at each cycle as would normally. occur due to the restoring cam 56 being provided. on the main shaft 2,

and restoration of a stop when not required is" prevented by the latch 49 which, when the latch out of engagement with. the squarepin 54, is moved into position beneath: a

The restoring cam 56 is provided with two humps 62 and 63, Figure 1B, of'which the hum'p': '63' is adapted to restore the card stops when a stock card is in the sensing chamber, while the: hump 62 is adapted to restore the card stop the spindle andfollower 85.

7 In operation the lower part of the pin box 66 comprising the plates 68 and the sensing pins 61, as described in specification No. 478,597, is reciprocated while the upper portion including the plates 10 and 12 remain stationary.

Between the plate 12 and the upper ends of the sensing pins is a plurality of disabling devices provided selectively to disable a predetermined group or groups of columns of sensing pins 61 during consecutive cycles of the main shaft 2. The disabling devices comprise four slotted shutter plates 14, 15, 16 and 11, Figure 10. The shutters are mounted for independent operation and are operated, in a manner similar to that described in United Kingdom specification No. 518,752, to permit the sensing pins 61 to sense consecutively a plurality of groups of hole positions in each of a plurality of parallel groups of vertical columns of index positions on a record card. The arrangement of the shutters is shown more clearly in Figures 9 and 10 taken in combination with Figure 5.

The sensing pin box 66, Figures 1B and 5, has, in the construction being described, sixty-five columns of sensing pins 61 and the shutter plate 14 controls one section of the pin box comprising columns one to eight, shutter 15 controls columns nine to thirty-three, shutter 16 controls columns thirty-four to fifty-eight, and shutter 11 controls columns fifty-nine to sixtyfive. The shutter 14 is provided with a latch 18 mounted on a control shaft 19, shutter 15 is provided with a latch 80 mounted on a control shaft 8|, shutter 16 is provided with two latches 82 and 83 of which the latch 82 is mounted on shaft 8| and the latch 83 is mounted on shaft 19, and shutter 11 is provided with a latch 84 mounted on shaft 19. The control shafts 19 and 8| are mounted in brackets 85, Figures 113 and 33, secured to the machine frame, an arm 96 being secured to one end of the shaft 8|, see Figure 33, while a corresponding arm 81 is secured to one end of the shaft 19. A link 88 is slotted to engage a pin 89 carried by arm 86 and at its opposite end carries a roller 90, Figure 11, which engages a cam 9| secured to shaft 1, being retained in engagement with the cam by a spring 92, Figure 3B. A second link 93 is connected to the arm 81 by a slot and pin connection as described above with reference to the link 88, and at its opposite end carries a cam roller 94 engaging a. cam 95 also on shaft 1. A spring 96 maintains engagement between cam 95 and roller 94. The links 88 and 93' are connected by springs 91 and 91a to the pins 89 and 89a in their respective levers 86 and 81.

The shutters 14 and 11 are each provided with a control arm 98, Figure 5, secured to a shaft 99 and the shutters 15 and 16 which are wider than the shutters 14 and 11 are each provided witn two arms 98 also mounted on the shaft 99. The control arms 98 co-operate with slots Hi0, Figure 10, to move the shutters against the action of springs |9| each time the shaft 99 is rocked.

When one of the shutters is moved against the action of its spring |9|, slots, not shown, formed in the shutter as described in the aforesaid speciflcation No. 518,752, hold the corresponding connecting elements 13 preventing them from swinging in a clockwise direction, as viewed in Figure 5, about their heads under the action of the springs associated with the transmission rods 1|. If, however, the shutter is moved in the opposite direction then the slots in the shutter permit the connecting elements 13 to swing in a clockwise direction, the action of these connecting elements being the same as the action of the similar elements described in the aforesaid speciiication No. 401,012. Thus, if a shutter is held against the action of its spring |0| then the corresponding columns of connection elements 13 cannot operate and the corresponding section of the pin box 66 is rendered inoperative. As is described in specification No. 518,752 the shaft 99 is rocked in a counter-clockwise direction, as viewed in Figure 5, when the pin box is at the bottom of its stroke thus tending to move each of the shutters 14, 15, 16 and 11 against their springs ||I|. During the greater part of the revolution of the main shaft 2, however, the shaft 99 is at the end of its travel in the clockwise direction so that each of the shutters, if free, will be moved to the left, Figure 5, by their springs NH.

The cams 9| and 95, however, operate during selected cycles of the main shaft 2 to actuate the latches 18, 80, 82, 83 and 84 so that, as will be described below, one or more of the shutters is locked in its pulled position while the remaining shutter or shutters is or are free to move. As can be seen from Figures 5 and 10, the latches are provided with hook members which engage in square holes I02 formed in extension pieces 103 secured to the shutters for movement therewith, and the operation of the shutters is similar to that of the shutters described in the aforesaid specification No. 518,752. In order that the latches may be snapped into and out of the square holes 102 in extension pieces I03 the latches engage the upper or undersides of the extension pieces, as the case may be, before entering the square holes. This action is accommodated by the slots in the links 88, 93 sliding over the pins 69 and 89a, Figure 3B, associated therewith thus permitting the latches to rest against the faces of the extension pieces. When the links 88 and 93 have made their full movement, the shaft 99 is rocked and the springs 91 or 91A permit the latches to snap into the square holes I02. The lost motion during this movement is taken up by the springs 91 and 91A.

As mentioned above, the shutters operate in a predetermined sequence, the cams 9| and 96 being profiled to obtain the desired sequence. During the first cycle of the main shaft 2 a posting card is in sensing position and the fields included in columns one to eight and fifty-nine to sixty-five of the card, see Figure 21, are to be sensed. In this instance, when the shaft 99 is rocked the shutters are all moved to the right as viewed in Figure 5. The cams 95, 9| then simultaneously rock shafts 19 and BI so that the upper latches 18, 82 and 84 are moved out of their square holes I02 while the latches and 83 engage their associated square holes I02. When the arms 98 are returned to starting po sition the shutters 14 and 11 are free to return under the influence of their associated springs |8| while the shutters 15 and 16 are retained in the pulled position by the latches 80 and 83. Thus, the sensing of columns one to eight and fiftynine to sixty-five of the posting card is effected and is transmitted to the printing mechanism as described below.

During the second cycle of main shaft 2 the stock card is in the sensing position and is arrested therein by the card stop 6 in a position which will be referred to as the inter-stage position, that is a position at which sensing can be effected of perforations formed in horizontal rows 255m the card between the normal horizontal rows 254 of the card, see Figure 23. In this, the second, cycle the cams 9I, 95 operate so that the latches 82 and 83 are open while latches 18, 80 and 84 are closed thereby permitting sensing of the inter-stage positions in columns thirty-four to fifty-eight of the stock card.

In the third cycle of the shaft 2 the card is still arrested by the stop 6 but cams 9 I, 95 operate to open the latches 80 and 83 to permit sensing of the stock card in columns nine to thirty-three, latches 18, 82 and 84 being closed.

During the fourth cycle of main shaft 2 the stock card is advanced slightly into the sensing chamber to be arrested by the card stop to permit sensing of the normal horizontal rows 254 of the card and in this, the fourth, cycle the latches 82 and 83' are both open thus freeing the shutter 16 and permitting the sensing of columns thirty-four to fifty-eight, the shutters 14, and 11 being in the latched positions.

In the fifth cycle of the main shaft 2 the latches 18, 80 and 84 are open thus permitting sensing of the normal horizontal rows of the card in columns one to thirty-three and fifty-nine to sixty-five, the shutter 16 being latched by both of the latches 82 and 03.

Type setting mechanism The type wheels I3 are set by mechanism similar to that described in the aforesaid specification No. 478,597 but as the mechanism differs in some respects to that described in the aforesaid specification it will be briefly described herein.

Referring to Figure 5, there is disposed above the pin box 66 a connection box containing a plurality of connection wires I04 of which the lower' ends are in register with the corresponding transmission rods 1| while the upper ends register with corresponding stops I05 in a stop basket I 06. Each stop I05 is normally held down by a spring I01.

There are twelve stops in each column, of which the two lefthand stops I051; and I 05b represent the letters A and B respectively.

Mounted in a frame I08, Figures 1A and 3A, disposed above the stop basket I06 is a plurality of type setting slides I09, one for each column of stops I05. The operation of these slides is as described in specification No. 478,597, but means to be described below are provided for preventing actuation of selected groups of slides when these slides are not required for operation. The slides I09 have teeth thereon to operate two sectors I I0 engaging gear wheels III which drive further gear wheels I I2 which, in turn, drive the type wheel I 3.

To prevent the slides I09 from moving forward in those columns in which sensing is not effected during a cycle of the main shaft 2, stops I I4 and I I5, Figures 5 and 16,. are provided to prevent the forward movement of the slides associated with columns nine to thirty-four and thirty-seven to sixty-five respectively. The stop 4 is mounted between two arms H6 and H1 which are pivoted to short levers H8 and H9 fixed to a tubular shaft I mounted. in bearings I2I,v I22 and I23.

The stop I I5 is supported by two arms I 24 and I25 pivoted to short levers I26 and I21 mounted on a spindle I28 which passes through the tubular shaft I23. Secured to one end of the tubular shaft I 20 is a short arm I29, Figure 1A, and a. similar short arm. I30 is secured to the end. of the spindle I28. A link I3 I is secured to the secured to the sides 10 arm I29 and a similar link I32 is secured to the short arm I30. The other ends of the links I 3| and I32 carry cam rollers I33 andv I34, Figure 13, respectively engaging cams I35 and I36 on the auxiliary shaft 1. The cams I35 and I36 thus operate in timed relation with the cams 9| and .95 and move the stop H4, H5 associated therewith into or out of engagement with slots I 31, Figure 5, formed in the slides I09. Thus when the shutter 15 is latched, as described above, the stop I I4 engages the slots I31 in the slides I09 associated with columns nine to thirty-three, preventing the slides so engaged from moving forward. Similarly when the shutter 16 is in latched position the stop II5 prevents the slides I09 associated with columns thirty-seven to sixty-five from moving forward.

When the machine is empty and no card is in the sensing pin box 66 the shutters 14, 15, 16 and 11 are prevented from moving in a manner similar to that described in specification No. 401,012. If none of the pins H is raised then all the slides I09 will run forward to the fixed stop I38, Figure 5. To prevent this action two latches I39, Fig.- ures 1A, 3A, and. 5, of which only one is shown, are fixed to a cross shaft I40 and engage with pins I4I on arms I42 which as described in specification No. 478,597 operate a control bar I43 normally retaining the slides in their rearward position as shown in Figures 1A, 3 and 5.

Print hammer mechanism The posting card when it has been fed from the sensing chamber is passed by feed rollers to the printing position in which it is located beneath the type wheels I3, being retained in desired horizontal line printing position by the card stop blocks I2. The card stop I2 is mounted on a U-shaped frame I44, Figures 12 and 13, resting on a plate I45 supported by stems I46 for vertical reciprocation between guides I 41, I48. The frame I44 is slidable on the plate I45 and a guide plate I49 over which the cards pass is provided with slots through which the card stop block of a card gate I2 can pass. In Figure 12, the stops I2 are shown in card arresting position in which they project above the card guide plate I 49. The stop blocks I2 are moved stepwise away from the type wheels, that is to the left of Figure 12, during the second, third, fourth and fifth cycles of the main shaft 2 so that the posting card is successively positioned in spaced horizontal line relation to receive impressions from the type wheels. To effect the movement of the stop blocks I2 to these various card arresting positions there are provided three quadrants I50, I50a, I50b mounted on a shaft I5I. The quadrant I50, Figure 3C, meshes with a rack I52 riveted to a link I53 the opposite end of which carries a cam roller I54 for operation by a cam I55 on the auxiliary shaft 1. The quadrants I 5011 and I50b, Figures 12 and 13, are pinned to the shaft I5I between the side frames of the machine and mesh with racks I52a and I52b, Figure 13, of the card stop frame I 44, the racks I52c and I521) being slidable in guides I52-d and I 52c secured to brackets mounted on the side frames of the machine. As the cam I55 is rotated, the stop blocks I2, through quadrants I50, I50a, and I50b and racks I52a and I52b are intermittently moved to their successive card arresting positions.

The stop blocks I2 are moved into and out of the card arrestingposition shown in Figure 12 by two members I56 which engage pins I51 mounted in brackets I58 secured to the under surface of the plate I45. The members I55 depress the stems I45 against the action of a spring, not shown, which spring urges the stop to the card arresting position shown in Figure 12. The two members I55 are supported for angular move ment by a rocking shaft I59 to which shaft is connected a short arm I50, Figure 30, the other end of which is pivoted to an actuating link IGI, Figures 313 and 3C. The other end of the actuating link I6I is adapted for engagement with an abutment I02 extending laterally from a plate I63 guided for lengthwise movement by fixed spindle I64, and a hammer control shaft I82. The plate I83 carries a cam roller I66 which is engaged by a cam I51 on the main shaft 2.

When a posting card is in printing position the stop blocks !2 are retained in the card arresting position for live successive cycles of the main shaft 2 and to ensure that the stop blocks are not withdrawn by the cam I51 on the main shaft 2 a trip link I88 is connected at one end to the actuating link ISI and at its other end to one arm of a bell crank I69 pivoted at I10 to the machine frame. The other arm I1I of the bell crank has connected thereto a link I12 the opposite end of which carries a cam roller I13, see Figure 11, the roller I13 being actuated by a cam I14 on the auxiliary shaft 1. The cam I14 is adapted to rock the arm I83 of the bell crank in a counterclockwise direction so that the actuating link IIiI is lowered out of the path of the abutment I62 so that, until the actuating link IBI is restored to the position shown in Figure 3B, the card stop blocks I2 remain in the raised position.

Printing is efiected by transmission rods I15, Figure 12, actuated by hammers I18. The hammers are each pivotally mounted on a spindle I11 each hammer comprising a bell crank as shown in the drawing. The longer arm of the bell crank carries a hammer head I18 the shorter arm normally engages a latch I19 holding the hammer back against the action of a spring I80.

Carried between arms I8I on a hammer control shaft I82 is a bail I83 which, when the control shaft I82 is rocked as described below, engages cam surface I84 on all the latches I19 and swings the latches out of engagement with the arms I85 of the bell cranks, whereupon the springs I80 cause the heads I18 smartly to strike a corresponding number of transmission rods I which, as shown in the drawings, are mounted in guides I86. Each transmission rod I15 is in register with a type on the corresponding type wheel I3 and serves to transmit the hammer blow through an inked ribbon I81, Figure 3B, and a posting card located in line printing position by the stop blocks :2, so that an impression is produced on the card. Each transmission rod I15 is fitted with a return spring I88 which is slightly heavier than the spring I80 on the corresponding hammer. The transmission rod I15 is moved by the energy of the hammer due to the swing but returns immediately from contact with the card.

When the hammer latch I19 is released, the hammer head I18 flies upwards under the infiuence of the spring I80 and the momentum causes it to drive its associated transmission rod I15 upwards. Immediately, however, the hammer movement is arrested the transmission rod I15 is lowered again as the spring I88 is stronger than spring I80.

As the hammer control shaft I82 rocks back again, the bail I83 restores the hammers which are then re-engaged by the latches I19 under the action of springs I89 connected to the latter.

Actuation of the control shaft I82 is obtained from the main shaft 2 to which is secured an eccentric i80, Figures 33 and 15, of which the eccentric strap I9I is provided at its end with a slot I92 to engage a pin I93 carried by an arm I94 secured to the hammer control shaft I82.

Mounted on the pin I93 is a plate I95 which is guided at its other end by a slot I95 through which the main control shaft 2 passes.

Pivoted to the eccentric strap I9I at I91 is a latch I98 which has a nose I99 and is connected by a link 200 to a lever 20I which lever rocks the shaft 99, Figures 313 and 5, to actuate the shutters 14, 15, 16, and 11 against the action of the springs IOI.

The plate I95 is formed with a shoulder 202 and a spring 283 is provided which tends to pull the pin I93 to the left in Figure 15.

Normally the parts are in the position shown in Figure 15 and, when a card in the sensing chamber is sensed, the lever 20I is permitted to rock clockwise in Figure 15. Consequently, link 200 permits the latch I98 to rock about its pivot I91 until its nose I99 engages with the shoulder 202 on the plate I95. Hence the movement of the eccentric strap I9I to the right in Figure 15 carries the latch I98 also to the right and takes with it the plate I95 since the shoulder 202 is engaged by the nose I99. This movement rocks the hammer control shaft I82 and releases the hammers as described above.

When a type Wheel is not set as a result of a sensing operation a card is normally printed with a horizontal dash and, as certain columns of a card are always blocked off from a sensing operation, the type wheels not set during the sensing operation would, as just mentioned, operate to print a series of dashes on a card in those columns in which sensing is not effected. To prevent the printing of dashes when these are not required there is provided mechanism now to be described.

Each hammer head I18 is provided with a notch 204, Figure 12, and three latches 205, 208 and 201, Figures 12 and 14, are provided to cooperate with the notches 204. The latch 205 is to control the hammers for printing in card columns one to eight, latch 205 is to control hammers for printing in card columns ten to thirty-four, and latch 201 is to control the hammers for printing in card columns thirty-seven to sixty-five. Fixed latches 208, 209 and 2I0 are provided permanently to cut out the hammers associated with card columns nine, thirtyfive and thirty-six.

The latch 205 is supported by a pair of arms 2, 2I2, while the latch 205 is supported by arms 2I3 and 2I4, and the latch 201 is supported by arms 2I5 and 2I5. The supporting arms are all guided for lengthwise movement in combs 2I1, 2I8, Figure 12. The latches are independently operated by cams 2I9, 220 and 22I secured to a shaft 222 driven by a stub shaft 223, Figure 14, through gears 224, 225. The stub shaft 223 is driven from the driving shaft 2a, Figure 13, by gearing not shown, and the cams 2I9, 220 and HI are timed to operate the latches 205, 205 and 201 in accordance with the movements of the shutters 14, 15, 15, and 11 so that the latches 205, 205 and 201 are effective to preat those times when the shutters associated vent firing of the hammers of the selected groups
